CASH-REGISTER.

Specification of Letters Patent.

Application filed January 27, 1908.

Patented May 17, 1910.

Serial No. 412,808.

To all whom it may. concern:

Be it known that I, FREDERICK HENRY TREVELLIAN, a subject of His Majesty the King of Great Britain and Ireland, residing at 71 Lambton Quay, Wellington, in the Provincial District of Wellington, in the Colony of New Zealand, have invented certain new and useful Improvements in Cash- Registers, of which the following is a specification.

This invention relates to cash registers having bands of paper whereon invoices and the like are to be written in duplicate, and the object of the invention is to provide improved mechanism whereby the said paper bands are traversed a short portion at a time below an opening in the casing of the register, prior to each opening of a cash drawer.

A further object of the invention is to provide improved mechanism for operating another band of paper whereon the total of each invoice is to be recorded.

The drawings herewith illustrate the invention:

Figure 1 is a plan of the register. Fig. 2 a plan with a lid of the casing removed.

. Fig. 3 a side elevation with the side of the casing removed. 'Fig. 4 a cross sectional elevation on line AA Fig. 3, of the register. Fig. 5 is a side elevation of a bell and its mechanism. Fig. 6 a sectional elevation of a roller and bearings, Fig. 7 a sectional elevation of a spring operated bearing, Fig. 8 an end elevation of a roller, Fig. 9 a perspective view of a pivoted plate and con nections, Fig. 10 a perspective view of a detent, Fig. 11 a perspective elevation of a clip, Fig. 12 a side elevation of a pawl and connections, Fig. 13 a sectional elevation, and Fig. 14 a side elevation of a pawl and connectlons, Fig. 15 is a lever for operating the clip.

The casing 1 inclosing the mechanism has a lid 2 hinged at 3 and contains a frame com prising side plates 4 and 5 hinged by a pin 6 to brackets 7 and 8 fixed to the back of the casin RoTlers 9 and 10 are journaled upon bearings consisting at one end of conical studs 11 and 12 fixed to the frame 4, and at the other end of conical studs 13 slidable in sockets 14 and 15, and having stems 16 and 17 projecting through the ends of the sockets and furnished with milled heads 18 and 19. Springs 20 in compression within the sockets tend to project the studs 13 from the sockets. The rollers can be readily removed by withdrawmg the spring studs 13. The springs 20 maintain the said studs in frictional contact with the rollers with sufficient pressure to prevent the rollers over-running. Bands of paper 21 and 22 are rolled upon the rollers 9 and 10, the band 21 passing toward and around the edge of a plate 27, fixed on the plates 4 and 5 by a screw 31, below an openmg 23 in the lid 2. The portion of the paper exposed in the opening is available for wrlting an invoice thereon. This band 21 then passes below a tension roller 24 around an end roller 25, and is finally coiled upon a receiving roller 26 to which its end is attached by any suitable adhesive matter. The band 22 passes upward and around a guide bar 28 thence over a spring clip 29 (see Fig. 11) to be hereafter described, below the roller 24 and its end passes out through a slot 37 in a plate 37 a covering the roller 24, and through the bottom of the opening 23.

The rollers are rotated to advance the pa per band by operating the handle 30, which is screwed upon or otherwise attached to a shaft 32, ournaled in the plates 4 and 5. A spur wheel 33 is secured to the shaft 32 in mesh with a second spur wheel 34 secured to a shaft 35, which latter is journaled in the lates 4 and 5. The wheel 33 is prevented rom turning in a reverse direction by a pawl 36 engaging the teeth of the wheel 34. A roller 38 secured upon the shaft 35 is located between the rollers 24 and 26.

The roller 26 is secured upon a shaft 39 guided in slots 40 in the plates 4 and 5 and supported upon arms 41 pivoted by a shaft 42 to the plates 4 and 5. A spiral spring 43 coiled around the shaft 42 has its ends 44 and 45 engaging the plates 4 and 5; a hook 46 formed in said spring engaging a cross bar 47 which unites the arms 41. The spring thus forces the roller 26 toward the roller 38.

The roller 24 is secured upon a shaft 49 mounted in arms 50 and 51 pivoted by pins 52 and 53 to the plates 4 and 5. The other ends of the arms are provided with screws 54 and 55 adapted to bear against plates 56 and 57 pivoted in brackets 58 and 59 secured to the plates 4 and 5. By adjusting the screws 54 and 55 the roller 24 is made to bear more or less heavily upon the roller 38. After the lid of the casing has been raised the roller 24 may be readily raisedby turning aside the plates 56 and 57 upon their pivots, the arms 50 and 51 are then free to be raised with their roller so that the paper bands may be readily placed in position. The paper, being thus gripped between the rollers 2 1, 38 and 26, 38, rotation of said roller 38 causes the paper to be wound from the roller 9 onto the roller 26. As the thickness of the paper roll on the roller 20 increases, the arms #11 will be pushed downward by the shaft 39 in the slot A0.

A single revolution of the handle revolves the roller 38 sufficiently to traverse or feed a portion of paper required for a single invoice only, which has been previously filled up by the operator through the opening 23. The pawl 36 prevents the handle being turned backward after a portion of a revolution has been made, and disarrangement of the paper bands is thus obviated.

The handle is prevented from turning more than a single revolution at one time by means of a bolt 60 slidable in brackets 01 and 02 fixed to the casing 1, and prevented from turning around in its brackets by a cross head (33, which bears against a plate (5 1 integral with the bracket 01. A spiral spring (35 located upon the bolt is in compression between the bracket 61 and a collar (36 secured upon the bolt. A head 67 projects laterally from the bolt ()0 in position for engagement by a curved cam 68 projecting laterally from the wheel 33. Vhen the handle 30 has revolved the wheel 33 throughout the greater part of a revolution the cam passes below the head (17 and raises the bolt 60 against the resistance of its spring and before the bolt falls, the stop 69 projecting laterally from the wheel 33 strikes the head 67 and arrests the handle 30.

The raising of the bolt 60, as just described, sets free a detent 70 (see Fig. 10) pivoted by a pin 71 to a plate 71 secured to the top of a base H of the register, the said detent being then free to move in the direction shown by the arrow. A lug 72, fixed to a till drawer 7 3 slidable in the said base 74 is normally retained by a groove 75 formed in the detent, but upon the bolt being raised the detent is free to be moved by the lug in the direction of the arrow. The lug is thus set free, and a spiral spring 76 in compression between the end of the base 7 1 and the drawer pushes the said drawer outward from the base. After the wheel 33 has completed a revolution, the cam 68 passes beyond the head 67 and allows the bolt to rest upon the upper surface of the detent 70, where it remains until the drawer is pushed inward, by which action the lug 72 is made to strike the projection 77 to return the detent to its original posi tion and thereby allow the bolt to fall into the groove 78 of the detent. The lug 7 2 is held in this position until the bolt 60 is again raised. The detent is prevented from moving too far, in a reverse direction by a pin 70 projecting downward from the plate 71.

aming that the drawer has been opened is given by a bell 80 (see Fig. 5) fixed to the side of the casing 1 by a stem 81. A hammer 82 pivoted upon a stud 83 fixed to the casing is normally held at rest against a pin 84, fixed to the casing, by a coil spring 85 located upon the said stud S3. A trigger S0 pivoted on the stud 83 has a tail 87 adapted to be struck by the end 88 of the drawer 73. A lug 89 of the trigger is adapted to engage a pin 90 projecting laterally from the hammer 82. lVhen the drawer is opened in the direction shown by the arrow the trigger operates the hammer, and being suddenly released by the end of the drawer, the trigger allows the hammer to strike the bell. Upon the drawer being pushed inward the trigger is tripped without operating the hammer, or ringing the bell.

A sl eet of carbon paper or silk 91 placed between the bands of paper 21 and 22 im mediately above the plate 27 is held in position by the spring clip 29, around which the paper band 22 passes. The clip 29 is cylindrical and has longitudinal lips 29 between which the carbon paper or silk is gripped. Brackets 29" integral with the lower part of the clip extend upward and are secured to the plates 1 and 5 by screws 29. The carbon paper is readily released and a fresh piece inserted by opening the clip, by means of a lever 93 (see Fig. 15), the bifurcated ends of which are adapted to engage in slots 95 formed in the top of the clip.

A band of paper 94: is employed whereon to rite the total of each invoice issued and as it is necessary to traverse this band a short distance only for each invoice, I provide the following mechanism for that purpose. The paper is coiled upon a roller 90 and passes over a plate 97 immediately below an opening 99 in the lid 2. The end of the paper is attached to another roller 100. The plate 97 is hinged by a pin 98 to the plates 1 and 5, for the purpose of providing room for the removal or introduction of the rollers 90 and 100. The roller 96 has conical bearings similar to the bearings of rollers 9 and 10 already described, but the roller 100 has the stem 101 of its springoperated conical bearing 102 provided with lugs 103, (see Figs. '7 and 8) which engage corresponding slots 104: in the end of the roller. A ratchet wheel 100 fixed upon the stem 101 is operated by a pawl 107 pivoted to a pin 109 fixed eccentrically in a disk 110 secured upon the end of the shaft Thus at each revolution of the handle 30, the pawl 107 rotates the ratchet wheel 106 a distance equal to the length of one of its teeth.

I have described the rollers 96 and 100 as placed in advance of the rollers 9 and 10 but if desired the said rollers 96 and 100 may be arranged side by side with the rollers 9 and 10, and Figs. 13 and 1 1 show mechanism whereby this arrangement may be effected. In this instance the casing 1 is widened and the rollers 96 and 100 are mounted in a separate frame 112, and the ratchet wheel 106 is fixed upon an end of the roller 100 projecting toward the plate 5. The shaft 32 is extended so that the pawl 113 may engage the ratchet wheel 106.

A sheet of glass 11 1 is fixed in the lid 2, through which the copy of the invoice is visible and may be read for purpose of comparison with the original, and similarly a sheet of glass 115 is provided in the said lid, through which copies of totals may be read.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a cash register provided with a drawer and with three traveling bands of registering paper, two of which are adapted to receive duplicate copies of invoices, the third being adapted to receive the total thereof, rollers for supporting the said bands and permitting their endwise travel, in combination with mechanism for causing such motion of the two bands first mentioned, mechanism distinct from said drawer for shifting one of said belts, a pawl and ratchet for operating one of the rollers to feed the third band and means operated by said band moving mechanism for automatically actuating said pawl and ratchet substantially as set forth.
